Thick? I don't think it's that thick. Thinner than my crusty Sony Ericsson (around 18mm) actually. It's definitely on the large side though, much like the EVO 4G and other phones with 4.3" screens. Obviously not for everyone, but some like the larger screens, or those who always have large pockets.

I want the Desire Z personally. Seems to have the right blend of features in a fairly typical smartphone size. Hopefully it doesn't take too long to arrive in Canada though...
